A BILL FOR

AN ACT concerning government.

Be it enacted by the People of the State of Illinois, represented in the General Assembly:

Section 1. Short title. This Act may be cited as the Definitions of Sex-Based Terms Act.

Section 5. Purpose; application; findings.

(a) The purpose of this Act is to bring clarity, certainty, and uniformity to the laws of the State regarding sex discrimination, privacy, equality of the sexes, and benefits or services specifically provided to males and to females.

(b) This Act shall apply wherever the State or an instrumentality of the State classifies people on the basis of sex or otherwise defines people as being female or male, women or men, girls or boys.

(c) The General Assembly finds that:

(1) males and females are legally equal, but they are not the same;

(2) males and females possess unique and immutable biological differences that manifest prior to birth and increase as they age and experience puberty;

(3) these unique and immutable biological differences mean that females and males are not similarly situated in all circumstances and are not interchangeable; and

(4) inconsistencies in court rulings and policy initiatives regarding sex discrimination and common sex-based words have endangered women's rights and resources and have put the existence of private, single-sex spaces in jeopardy, thereby necessitating clarification of certain terms used in State law.

Section 10. Definitions of terms used in State statutes and administrative rules. In determining the meaning of any statute or of any rule, regulation, or interpretation of the various administrative agencies of this State:

"Boy" means a human male who is a legal minor under the laws of Illinois, provided that the use of "boy" in reference to the participation of a high-school-aged individual in a school or extracurricular program shall not be understood to exclude the participation of a student who is legally an adult.

"Father" means a male parent of a child or children as defined in Illinois law.

"Female" means, when this term is used in reference to a natural person, an individual who naturally has, had, will have through the course of normal development, or would have but for a developmental anomaly, genetic anomaly, or accident the reproductive system that at some point produces ova.

"Girl" means a human female who is a legal minor under the laws of Illinois, provided that the use of "girl" in reference to the participation of a high-school-aged individual in a school or extracurricular program shall not be understood to exclude the participation of a student who is legally an adult.

"Male" means, when this term is used in reference to a natural person, an individual who naturally has, had, will have through the course of normal development, or would have but for a developmental anomaly, genetic anomaly, or accident the reproductive system that at some point produces sperm.

"Man" means an adult human of the male sex.

"Mother" means a female parent of a child or children as defined in Illinois law.

"Sex" means, when this term is used to classify or describe a natural person, the state of being either male or female as observed or clinically verified at birth. "Sex" includes only 2 sexes, and every individual is either male or female, and individuals with congenital and medically verifiable differences in sex development, disorders in sex development, or intersex conditions, are not members of a third sex and must be accommodated consistent with State and federal law. "Sex" does not include "gender identity" or any other term intended to convey a person's subjective sense of self; "gender identity" and other subjective terms are not synonyms or substitutes for "sex".

"Woman" means an adult human of the female sex.

Section 97. Severability. The provisions of this Act are severable under Section 1.31 of the Statute on Statutes.
